DETAILS OF THE INVENTION
The compounds of Formula I, where Q is Q-1, can be prepared by the reaction of hydrazones of Formula II with an aryl isocyanate of Formula III. Compounds of Formula I, where Q is Q-2 through Q-8, can be prepared by procedures which are analogous to those for compounds where Q is Q-1; therefore, for brevity only the Q-1 compounds are described. Typical reactions involve combination of equimolar amounts of II and III in a suitable solvent at temperatures generally in the range of -10° to 100° C. Although the reaction can be run neat, a solvent is generally preferred. Suitable solvents typically have sufficient polarity to effect solution of the Formula II hydrazone and include, but are not limited to, ethers such as diethyl ether, tetrahydrofuran and dioxane; halogenated hydrocarbons such as methylene chloride, chloroform and carbon tetrachloride; aromatic hydrocarbons such as benzene, toluene and xylene; esters such as ethyl acetate and polar aprotic solvents such as dimethylformamide and dimethylacetamide. ##STR6##
Compounds of Formula I include both geometrical and optical isomers as well as syn and anti isomers around the nitrogen-nitrogen bond. These isomers may vary in their biological activity. In some instances, it may be desirable to obtain compounds which are geometrically and/or optically pure or which are enriched in one or more of the possible isomers. All such isomers are included within the scope of this invention.
For the sake of simplifying the description of this invention, the generic formula (Formula I) encompasses certain compounds that may have long term stability problems and/or are difficult to prepare. For example, when R1 is an OCO2 R8 group and R8 is hydrogen the R1 substituent is OCO2 H which will decompose to the corresponding phenol and carbon dioxide. Similarly, haloalkylamines when R1 is NR8 R9 and R8 is C1 to C6 haloalkyl are unstable when the halo substituent is directly adjacent to nitrogen. These generally decompose to the corresponding hydrogen halides and imine. These compounds, however, are relatively few; their identity would be obvious to one skilled in the art, and their excision from the scope would unduly complicate and lengthen the description of the invention.
The hydrazones of Formula II can be obtained by processes known in the art involving condensation of a ketone of Formula IV with either hydrazine or a substituted derivative thereof (Formula V). This reaction is typically conducted with equimolar amounts of IV and V although greater than stoichiometric amounts of hydrazine (V) can be used. Suitable solvents include the alcohols such as methanol, ethanol, propanol, butanol and the like at temperatures in the range of 0° to 150° C., with the reflux temperature of the solvent generally being a convenient reaction temperature. Acid catalysis can also be useful, particularly for some of the more sterically hindered Formula IV compounds. Typical acid catalysts include sulfuric, hydrochloric and p-toluene sulfonic acid. ##STR7##
An alternate process useful for the preparation of compounds of Formula I involves condensation of a phenyl substituted semicarbazide of Formula VI with a ketone of Formula III. Preferred conditions for this reaction include an acid catalyst such as hydrochloric, sulfuric or p-toluene sulfonic acid. Reaction temperatures can range from 0° to 150° C. with the reflux temperature of the solvent used generally preferred. Suitable solvents include, but are not limited to, ethers such as tetrahydrofuran and dioxane; aromatic hydrocarbons such as benzene and toluene; and especially preferred are alcohols such as methanol, ethanol and isopropanol. ##STR8##
Compounds of Formula I where R5 and R6 are other than hydrogen can generally be prepared from the corresponding compounds where R5 and R6 are hydrogen by reaction with electrophilic reagents such as alkyl halides, acyl halides, alkyl chloroformates and sulfenyl halides. The use of a base is generally preferred in these reactions but is dependent upon the specific nature of the reactants. For example, when the electrophilic reagent is selected from an alkyl halide, acyl halide or alkyl chloroformate, then metal hydrides such as sodium hydride or potassium hydride in solvents such as tetrahydrofuran or dimethylformamide are preferred. When sulfenyl halides are used then amine bases such as triethylamine in solvents such as diethyl ether or tetrahydrofuran are generally preferred. Of course, many of the compounds where R5 is other than H can also be prepared by use of the appropriate hydrazine V in Scheme 2. For example, methyl hydrazine and methyl carbazate will produce compounds where R5 is methyl and carbomethoxy, respectively.
The starting ketones of Formula II are known or can be obtained by processes analogous to known ones. Those skilled in the art will recognize the Formula II compounds to include indanones, tetralones, chromanones, thiochromanones, benzofuran-3-ones, thiobenzofuran-3-ones, isochromanones, isothiochromanones and others.

The product was obtained as a white powder (0.26 g, 2 2% yield). m.p.=158°-160° C. 1 H NMR (CDCl3) δ: 8.45 (1H, s), 8.15 (1H, d, J=9 Hz), 7.98 (1H, s), 7.61 (5H, m), 7.29 (2H, m), 7.18 (2H, m), 6.92 (1H, dd, J=3,9 Hz), 6.75 (1H, d, J=3 Hz), 4.18 (1H, m), 2.64 (2H, m), 2.31 (1H, m), 2.10 (1H, m).
EXAMPLE 7 Step A: 4- Chloro-2-(2-methoxy-1-methyl-2-oxoethoxy)benzoic acid, methyl ester
A solution of methyl 4-chlorosalicylate (5.0 g) in dimethyl formamide (10 ml) was treated sequentially with methyl 3-bromopropionate (4.0 g) and potassium carbonate (6.0 g). The mixture was stirred at room temperature for 18 hrs and diluted with water. The mixture was extracted with ether and the organics were washed with water. The organic layer was dried and evaporated to give the desired material (6.7 g) as a low melting solid. NMR: 7.8 (d, 1H), 7.2 (m 1H), 6.9 (m, 1H), 4.8 (q, 1H), 3.9 (s, 3H), 3.8 (s, 3H), 1.7 (d, 3H).
Step B: 6-chloro-2-methyl-3(2H)-benzofuranone
A mixture of the compound of Example 7, Step A, (6.7 g) and sodium hydride (60% in oil, 1.5 g) was heated to reflux in tetrahydrofuran (50 ml). It Was then allowed to cool to room temperature over 1.5 hrs. The cooled mixture was treated with aqueous ammonium chloride solution and ether. The ether solution was dried over magnesium sulfate and then evaporated. The oil was subjected to chromatography on silica gel with hexanes/ethyl acetate (25:1) as the eluent. The desired product (1.99 g) was obtained as a low melting solid. NMR: 7.6 (d, 1H), 7.1 (m 2H), 4.7 (q, 1H), 1.55 (d, 3H).
Step C: (Z)-2-(6-chloro-2-methyl-3(2H)-benzofuranylidene)-N-[4-(trifluoromethyl)phenyl]hydrazinecarboxamide
The compound of Example 7, Step B, (1.9 g) was dissolved in ethanol (15 ml) and degassed with nitrogen. Then hydrazine hydrate (1.2 ml) was added and the mixture was heated at reflux for 1.5 hrs and evaporated to dryness. The residue was chromatographed on silica in hexanes/ethyl acetate (2:1). The first product eluted was the hydrazone syn to the methyl group (0.5 g). The next fraction (0.9 g) was mixed syn and anti. Pure anti hydrazone was eluted last (0.5 g). The syn hydrazone was treated with p-trifluoromethylphenylisocyanate (0.4 ml) in ether (10 ml). The desired material began to crystallize soon after mixing. The mixture was filtered and washed with ether to provide a solid (0.8 g). m.p.: 196°-198° C. NMR: 10.0 (br, 1H), 9.4 (br, 1H), 8.2-7.0 (m, 7H), 5.35 (m, 1H), 1.6 (d, 3H).
Step D: (E)-2-(6-cloro-2-methyl-3(2H)-benzofuranyl idene)-N-[4-(trifluoromethyl)phenyl)hydrazinecarboxamide
Treating the anti hydrazone (0.5 g) obtained in Step C with P-trifluoromethylphenylisocyanate (0.4 ml) in the same manner as in Step C resulted in the isolation of the desired product as a solid (0.8 g). m.p. - 205°-207° C. NMR: (10.4 (br, NH), 9.4 (br, 1H), 8.2-7.0 (m, 7H), 5.8 (m, 1H), 1.47 (d, 3H).

Arthropodicidal Formulation and Use
The compounds of this invention will generally be used in formulation with a carrier comprising a liquid or solid diluent or an organic solvent. Useful formulations of the compounds of Formula I can be prepared in conventional ways. They include dusts, granules, pellets, solutions, suspensions, emulsions, baits, wettable powders, emulsifiable concentrates, dry flowables and the like. Many of these can be applied directly. Sprayable formulations can be extended in suitable media and used at spray volumes of from about one to several hundred liters per hectare. High strength compositions are primarily used as intermediates for further formulation. The formulations, broadly, contain about 1% to 99% by weight of active ingredient(s) and at least one of a) about 0.1% to 20% surfactant(s) and b) about 5% to 99% solid or liquid diluent(s). More specifically, they will contain these ingredients in the following approximate proportions:

Lower or higher levels of active ingredient can, of course, be present depending on the intended use and the physical properties of the compound. Higher ratios of surfactant to active ingredient are sometimes desirable, and are achieved by incorporation into the formulation or by tank mixing.
Typical solid diluents are described in Watkins, et al., "Handbook of Insecticide Dust Diluents and Carriers", 2nd Ed., Dorland Books, Caldwell, N.J. The more absorptive diluents are preferred for wettable powders and the denser ones for dusts. Typical liquid diluents and solvents are described in Marsden, "Solvents Guide," 2nd Ed., Interscience, New York, 1950. Solubility under 0.1% is preferred for suspension concentrates; solution concentrates are preferably stable against phase separation at 0° C. "McCutcheon's Detergents and Emulsifiers Annual", Allured Publ. Corp., Ridgewood, New Jersey, as well as Sisely and wood, "Encyclopedia of Surface Active Agents", Chemical Publ. Co., Inc., New York, 1964, list surfactants and recommended uses. All formulations can contain minor amounts of additives to reduce foam, caking, corrosion, microbiological growth, etc. Preferably, ingredients should be approved by the U.S. Environmental Protection Agency for the use intended.
The methods of making such compositions are well known. Solutions are prepared by simply mixing the ingredients. Fine solid compositions are made by blending and, usually, grinding as in a hammer or fluid energy mill. Suspensions are prepared by wet milling (see, for example, U.S. Pat. No. 3,060,084). Granules and pellets can be made by spraying the active material upon preformed granular carriers or by agglomeration techniques. See Browning, "Agglomeration", Chemical Engineering, Dec. 4, 1967, pages 147 and following, and "Perry's Chemical Engineer's Handbook", 4th Ed., McGraw-Hill, New York, 1963, pages 8 to 59 and following.

insect pests of the order Mallophaga and Anoplura including the head louse, body louse, chicken head louse and other sucking and chewing parasitic lice that attack man and animals;
insect pests of the order Siphonoptera including the cat flea, dog flea and other fleas.
The specific species for which control is exemplified are: fall armyworm, Spodoptera fruigiperda; tobacco budworm, Heliothis virescens; boll weevil, Anthonomus grandis; aster leafhopper, Macrosteles fascifrons; southern corn rootworm, Diabrotica undecimpunctata. The pest control protection afforded by these compounds of the present invention is not limited, however to these species.
Application
Arthropod pests are controlled and protection of agronomic crops, animal and human health is achieved by applying one or more of the Formula I compounds of this invention, in an effective amount, to the locus of infestation, to the area to be protected, or directly on the pests to be controlled. Because of the diversity of habitat and behavior of these arthropod pest species, many different methods of application are employed. A preferred method of application is by spraying with equipment that distributes the compound in the environment of the pests, on the foliage,-animal, person, or premise, in the soil or animal, to the plant part that is infested or needs to be protected. Alternatively, granular formulations of these toxicant compounds can be applied to or incorporated into the soil.
Other methods of application can also be employed including direct and residual sprays, aerial, baits, eartags, boluses, foggets, aerosols, and many others. The compounds can be incorporated into baits that are consumed by the arthropods or in devices such as traps and the like which entice them to ingest or otherwise contact the compounds.
The compounds of this invention can be applied in their pure state, but most often application will be of a formulation comprising one or more compounds with suitable carriers, diluents, and surfactants and possibly in combination with a food depending on the contemplated end use. A preferred method of application involves spraying a water dispersion or refined oil solution of the compounds. Combinations with spray oils, spray oil concentrations, and synergists such as piperonyl butoxide often enhance the efficacy of the compounds of Formula I.
The rate of application of the Formula I compounds required for effective control will depend on such factors as the species of arthropod to be controlled, the pest's life cycle, life stage, its size, location, time of year, host crop or animal, feeding behavior, mating behavior, ambient moisture, temperature, etc. In general, application rates of 0.05 to 2 kg of active ingredient per hectare are sufficient to provide large-scale effective control of pests in agronomic ecosystems under normal circumstances, but as little as 0.001 kg/hectare or as much as 8 kg hectare may be required. For nonagronomic applications, effective use rates will range from about 0.1 to 5 mg/square foot but as little as about 0.01 mg/square foot or as much as 15 mg/square foot may be required.
The following Examples demonstrate the control efficacy of compounds of Formula I on specific pests; see Tables 1 to 10 for compound descriptions. Compounds followed by a dash in the percent mortality column were either not screened or had less than 80% mortality on the test species.
EXAMPLE 8 Fall Armyworm
Test units, each consisting of an 8-ounce plastic cup containing a layer of wheat germ diet, approximately 0.5 cm thick, were prepared. Ten third-instar larvae of fall armyworm (Spodoptera frugiperda) were placed into each cup. Solutions of each of the test compounds (acetone/distilled water 75/25 solvent) were sprayed onto the cups, a single solution per set of three cups. Spraying was accomplished by passing the cups, on a conveyer belt, directly beneath a flat fan hydraulic nozzle which discharged the spray at a rate of 0.5 pounds of active ingredient per acre (about 0.55 kg/ha) at 30 p.s.i. The cups were then covered and held at 27° C. and 50% relative humidity for 72 hours, after which time readings were taken. The results are tabulated below.

EXAMPLE 10 Aster Leafhopper
Test units were prepared from a series of 12-ounce cups, each containing oat (Avena sativa) seedlings in a 1-inch layer of sterilized soil. The test units were sprayed with individual solutions of the below-listed compounds. After the oats had dried from being sprayed, between 10 and 15 adult aster leafhoppers (Mascrosteles fascifrons) were aspirated into each of the covered cups. The cups were held at 27° C. and 50% relative humidity for 48 hours, after which time mortality readings were taken. The following table depicts the activity of the compounds tested on aster leafhopper.

EXAMPLE 11 Southern Corn Rootworm
Test units, each consisting of an 8-ounce plastic cup containing 1 sprouted corn seed, were prepared. Sets of three tests units were sprayed as described in Example 8 with individual solutions of the below-listed compounds. After the spray on the cups had dried, five third-instar larvae of the southern corn rootworm (Diabrotica undecimpunctata howardi) were placed into each cup. A moistened dental wick was inserted into each cup to prevent drying and the cups were then covered. The cups were then held at 27° C. and 50% relative humidity for 48 hours, after which time mortality readings were taken. The results are tabulated below.
